HAND-STAMP.

SPECIFICATION forming part of Letters Patent No. 392,229, dated November6, 1888,

Application filed October 12, 1886. Serial No. 215,989.

To all whom it may concern:

Be it known that we, WILLARD W. SAW- YER, a resident of Springfield, inthe county of Hampden and State of Massachusetts, and

WILLIAM A. FORCE, a resident of Brooklyn, in the county of Kings andState of New York,

have jointly invented an Improved Hand-` Stamp, of which the followingis a full, clear, and exact description, reference being made to theaccompanying drawings, in which- Figure l is a face View of our improvedhand-stamp, the apron or cap being partly broken away. Fig. 2 is a crosssection of the same on the line x a?, Fig. l, but showing the printingapparatus reversed. Fig. 3 is a top View, partly in section, of theplaten and printing devices of the handstamp in the position representedin Fig. 2. Fig. Ll is a vertical section on the line y y, Fig. 2.

This invention relates to improvements in that class of hand-stampswhich carry series of printing or type bands on a revolving printingplate or platen. These type bands in stamps of this character areusually of indiarubber and carry projecting rubber types. Stamps of thisclass ordinarily have three typebands, one being the day-band, thesecond the month-band, and the third the year-bandthat is to say, theday-band has types for printing the numerals ofthe days of the monthfrom 1 to 3l, inclusive, the month band carries types expressing thenames of the twelve months of the year, while the year-band carriestypes expressing certain years, and sometimes, also, types expressingsuch phrases as Received,7 Answered,7 Accepted,7 Entered, 1.3aid,77 Src.It will not be overlooked thatl the day-band of such a stamp hasthirtyone types,while the month-band and the yearband need not have morethan Vtwelve types each; hence the day-band must be much longer thaneither of the other bands, or else the types on the month and year bandsare unduly spread apart thereon, so that they may be as long as theday-band. When these bands are applied to a handstamp having a revolvingplaten, the principal difficulty in the way of their employment lies inthe greater length of the afore-Y No modeL) The principal feature of ourpresent invention consists in combining the day-band ofsnch a stamp withfour carriers, by which it is compacted on the stamp in such manner asto reduce its length, and thereby, also, the length of the stamp.

The second feature of our invention relates to the mechanism,hereinafter described, for adjusting the distance of the printing-typebeyond the face of the platen or die-plate, and to other phases ofimprovement that will be hereinafter more fully specied.

In the accompanying drawings, the letter A represents the maincarrying-frame of our improved hand-stamp, the same consisting of ahandle, a, and lower yoke, b.

B is the vertically-movable lower frame of the stamp, which is straddledby the yoke b,

and which carries the inking-pad d on the under side of its top plate,e.

C is the platen or printing-plate. The ends of this platen are by pins fpivoted in the lower end of the yoke b, while pins q on the frame -Bengage wit-l1 projections 71, on the platen for the purpose of revolvingthe same on its pivots fwhenever the frame B is slid into the frame Afrom the position shown in Fig. l, or out of it from the position shownin Fig. 2.

The frame B has an upwardly-projecting stem, l,which enters the handlea, that contains a suitable spring for normally holding the frame B inthe lower position,which is indieated in Fig. l.

All these parts A I3 C, their connections with one another, and themeans employed for turning the platen O do not constitute part of ourpresent invention, but are recognized by us as Well-known contrivances.

The platen C is slotted, as in Figs. 2 and 4, to let the printing-bandsbe passed through it. These printing-bands D, E, and F are carried inand by a frame, G, which at its ends has projecting ears j, throughwhich are passed screws k, that enter nuts Z, whichv are rigidlyattached to the non-printing side of the platen C. The screws k la haveheads or shoulders above and below the ears j, so that on turning saidscrews the frame G will be moved up or down in the platen. This isv forthe purpose of making the printing portion of each type IOO band projectthe exact distance required, and no fart-her nor less, from theprinting-face of the platen. This printing-face of the platen hasattached to it in all ordinary cases a dieplate, II, of india-rubber orthe like, which must be renewed from time to time. The differentdie-plates H are not always ot' the same thickness, hence the necessityof properly and exactly adjusting the frame .(l, which carries thetypo-bands.

The frame tl consists of two side plates, ym, which are connected by abridge or cross-bar, n, into one rigid structure. Calling that end ofthe frame G which carries the bridge or cross-bar nthe lower end,(because in printing said bridge is at the lower part of the stamp, asinFig. 2,) the upper end of the frame G carries two sets of rollers orband-supports, o o. The month and year bands D F are placed over therollers or supports o 0 and bridge a; but the day-band E, which islonger than the bands D and F, is, between the supports o o, carrieddown around another roller or support, p, which, as shown in Fig. 4, ishung in projections of the bridge a. Thus the longer dayband, E, beingpassed under the bridge n and supports o o and p, is compacted into thesaine extent as the shorter bands, l) and F.

The upper side of the platen C,calling that the upper side which is suchin lig. 2 of the drawings, has also attached to it an apron or cap, I,which incloses the lrame G and the bands D E F and their supports, l'orthe purpose of protecting them from dust or the like. On opposite sidesthis apron has slots or openings (bthrongh which the lingers of theoperator can reach portions ot' the bands D E F, l'or the purpose ofturning them to bring dit ferent types into the printing` position.Above l and below each of these slots the apron I has on its inner sidewipers 1', of l'elt or the like, which wipe the ink ol't' the type thatis being moved in line with the slots q.

In order to enable the linger ol' the attend` ant to grasp, whenneccssary,themiddle band, l

E, and move the same individually, we have caused the saine to projectavery little beyond the bands D F at the place where the slots q are inthe housing. This is cffectuated by thickening the rollers or supports oin the iniddle, where the band E passes over them, as shown at s iu Fig.fl. Vv'ere it not for this the operator might have difficulty inattempting to turn the band Fi alone.

NVe elaim-- '1. In a handstamp, the combination ol' the endlessprinting-band ll with the lower support, a, double upper supports, o o,and intermediate support, p, whereby said band E is doubled orcompacted, the support p being directly above the support a,substantially as herein shown and described.

2. In al hand-stamp, the combination of the type-band traine G, havinglower type-band support, a, double upper supports, o o, and intermediatesupport, p, with the type-bands D E F, certain ol' said type-bands beinglaid over three supports, va 0 o, and certain over four supports, n, o0, and p, substantially as and for the purpose specitied.

3. The combination of the perforated platen C, carrying the nuls Z onits non-printing side, with the type-band-carrying frame G, having lugsj, and with the screws It, having heads above and below the lugs j,swiveled in said lugs, and engaging with said nuts l, as speci fied.

Al. The combination of the slotted apron l with the series ol'type-bands which it incloses, and willi the wipers r r,that arecontained on the inner sides ot said apron, as specified.
